The organizations described in IRC Section 501(c)(3) are commonly referred to under the general heading of "charitable organizations." Organizations described in IRC Section 501(c)(3), other than testing for public safety organizations, are eligible to receive tax-deductible contributions in accordance with IRC Section 170.

The exempt purposes set forth in IRC Section 501(c)(3) are charitable, religious, educational, scientific, literary, testing for public safety, fostering national or international amateur sports competition, and the prevention of cruelty to children or animals. The term charitable is used in its generally accepted legal sense and includes relief of the poor, the distressed, or the underprivileged; advancement of religion; advancement of education or science; erection or maintenance of public buildings, monuments, or works; lessening the burdens of government; lessening of neighborhood tensions; elimination of prejudice and discrimination; defense of human and civil rights secured by law; and combating community deterioration and juvenile delinquency.

To be organized exclusively for a charitable purpose, the organization must be a corporation, community chest, fund, or foundation. A charitable trust is a fund or foundation and will qualify. However, an individual or a partnership will not qualify. The articles of organization must limit the organization's purposes to one or more of the exempt purposes set forth in IRC Section 501(c)(3) and must not expressly empower it to engage, other than as an insubstantial part of its activities, in activities that are not in furtherance of one or more of those purposes. This requirement may be met if the purposes stated in the articles of organization are limited in some way by reference to IRC Section 501(c)(3). In addition, assets of an organization must be permanently dedicated to an exempt purpose. This means that should an organization dissolve, its assets must be distributed for an exempt purpose described in this chapter, or to the federal government or to a state or local government for a public purpose. To establish that an organization's assets will be permanently dedicated to an exempt purpose, the articles of organization should contain a provision insuring their distribution for an exempt purpose in the event of dissolution. Although reliance may be placed upon state law to establish permanent dedication of assets for exempt purposes, an organization's application can be processed by the IRS more rapidly if its articles of organization include a provision insuring permanent dedication of assets for exempt purposes. For examples of provisions that meet these requirements, download Publication 557, Tax-Exempt Status for Your Organization.

An organization will be regarded as "operated exclusively" for one or more exempt purposes only if it engages primarily in activities which accomplish one or more of the exempt purposes specified in IRC Section 501(c)(3). An organization will not be so regarded if more than an insubstantial part of its activities is not in furtherance of an exempt purpose. For more information concerning types of charitable organizations and their activities, download Publication 557.

The organization must not be organized or operated for the benefit of private interests, such as the creator or the creator's family, shareholders of the organization, other designated individuals, or persons controlled directly or indirectly by such private interests. No part of the net earnings of an IRC Section 501(c)(3) organization may inure to the benefit of any private shareholder or individual. A private shareholder or individual is a person having a personal and private interest in the activities of the organization. If the organization engages in an excess benefit transaction with a person having substantial influence over the organization, an excise tax may be imposed on the person and any managers agreeing to the transaction.

IRC section 501(c)(3) organizations are restricted in the amount of political and legislative (lobbying) activities they may conduct. For a detailed discussion, see Political and Lobbying Activities.
